The Atomic Fingerprint Bernard Keisch. One of two or more atoms having the same atomic number but different mass numbers. Published by Houghton Mifflin Company. Remark 1. Some authors abbreviate ambient isotopy to just isotopy. Readers should be careful to clarify the meaning of isotopy in a particular text. Two embeddings and are called isotopic if there is an isotopy between them.

Isotopy defines an equivalence relation on the set of embeddings of into in the smooth category this is non-trivial, see [ Hirsch , 8, Theorem 1. In the smooth category isotopy is also called diffeotopy by some authors.

The set of embeddings of into can be topologised in such a way that an isotopy is equivalent to a continuous path of embeddings.

The fact that each isotope has one proton makes them all variants of hydrogen: the identity of the isotope is given by the number of protons and neutrons. From left to right, the isotopes are protium (1 H) with zero neutrons, deuterium (2 H) with one neutron, and tritium (3 H) with two neutrons.

  2. Aug 08,  · The relative isotopic mass is a unitless quantity with respect to some standard mass quantity. The relative atomic mass can be taken as the weighted mean mass of an atom of an element compared to the mass of 1/12 of the mass of an atom in C
  3. Isotope, one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behaviour but with different atomic masses and physical properties. Every chemical element has one or more isotopes. An atom is first identified and labeled according to the number of protons in its nucleus.
  4. The masses employed in calculating the moments and products of inertia must correspond to a single isotope for each atom in the molecule. Since the principal moments of inertia are different for different isotopic forms of a molecule, quite different rotational spectra are obtained. In fact, if the molecular mass distribution in a molecule is changed, the rotational spectrum is affected.
  5. Dec 21,  · The isotopic dipole moment, pointing from D to H, is then calculated for the first time, yielding ( ± ) × 10−3 Debye, being helpful in the interpretation of experiments.
  6. The masses employed in calculating the moments and products of inertia must correspond to a single isotope for each atom in the molecule. Since the principal moments of inertia are different for different isotopic forms of a molecule, quite different rotational spectra are obtained.
  7. Aug 05,  · Here, DFT calculations are reported for the isotopic effects on dipole moments of molecules with increasing permanent dipole moments, namely propane (μ ≃ debye), propyne (μ ≃ debye) and water (μ ≃ debye). The results account well for the experimental values and isotopic trends of the dipole moments of these molecules.
  8. peak. We can call this the isotopic rank. Let E be a chemical element. Let ˇE[i]denote the probability of the isotope of E having i additional mass units. Thus the relative intensities of the isotopic peaks for a single atom of element E are (ˇE[0],ˇE[1],ˇE[2],,ˇE[kE]). Here kE denotes the isotopic rank of the heaviest isotope occurring in nature.
